Application filed February 12, 1390. Serial No. 340,202. (No model.)

To all whom it may concern:

Be it known that I, HERBERT A. WRIGHT, of Detroit, in the county of-Wayne and State of Michigan, have invented a new and useful Improvementin Apparatus for Operating the Platen and Paper-Carriage of aType-\Vriting Machine, of which the following is aspecification.

My invention consists in an improved apparatus for operating the platenand paper-carriage of a type-writing machine hereinafter fully describedand claimed.

Figure 1 is a plan View of a type-writing machine. Fig. 2 is a sectionof the top plate of the machine and the paper-carriage frame, taken onthe line a: to, Fig. 1, looking from the right. Fig. 3 is-a section ofthe machine on the line 3 y, Fig. 1, looking from the front,

the paper-carriage being removed and the upper portions of the hangerssupporting the ribbon-spool actuating-bar being broken away. Fig. 4 is arear elevation of the machine, the paper-carriage being removed. Fig. 5is an enlarged section of the rear portion of the machine on the line .2.2, Fig. 1, the paper-carriage being removed. Fig. 6 is an elevation ofa part of the paper-carriage-actuating apparatus removed from themachine. Fig. 7 is an isometric view of a portion of thepaper-carriage-actuating apparatus not shown in Fig. 6. Fig. 8 is adetail view of the double cams. Fig. 9 is a detail view illustrating oneof the operations of the device. Fig. 10 is an elevation showing amodification of the papercarriage-actuat-ingmechanism. Figs. 11 and 12are enlarged detail views of the platenturning apparatus, as shown inFigs. 1 and 2, and Fig. 13 is an enlarged detail section of the rodsimilar to that shown in Fig. 5.

In all the views the type-hammers and the rods connecting them with thelevers are omitted.

The object of my invention is to movethe paper-carriage transverselyacross the machine to provide for the spacing of the letters and words,to return said carriage to thep0si, tion for commencing a line eitherautomati ence being had to the accompanying drawlugs.

A is the frame, and B the top plate, of a type-writing machine.

C are the keys.

D is the spacing-bar, and Ethe levers upon which the keys andspacing-bars are mounted. I

F is the frame of the paper-carriage.

G is the rod for guiding the motion of the paper-carriage.

H H are journal-lugs extending from the frame F of the paper-carriageand passing around the guide-rod G.

At I is placed the usual helical spring, which draws by means of a strapor cord 1' upon the paper-carriage. Said spring, when used in connectionwith my invention, is placed at the right of the machine and acts todraw the paper-carriage toward itself to the position for commencing aline of the manuscript upon the platen.

J is a rod a little longer than the distance traveled by thepaper-carriage.

jj are journal-lugs of equal length extending from each end of the rod Jat right angles thereto and holding said rod parallel to the guide-rodG. The j on rnal-lugsjj are provided with circular holes in their endsin which the guide-rod G can turn and slide. The distance between theinside faces of the lugs jj is equal to the distance between the outsidefaces of the lugs H H.

a, Fig. 7, is arectangular slot formed in the lower edge of the rod Jthroughout its entire length. I

K is a horizontal rack-bar secured to the 1 forward side of the rod J.

Zlare screws passing through slots k 1:, cut through the rack-bar K andinto the rod J. By means of the screws Z l and the slots is k therack-bar has a vertical movement, but is restrained from any horizontalmovement relative to the rod J. The lower edge of the rack-bar K isprovided with teeth adapted to engage with the teeth of the wheel.

S L L are springs secured at one of the journal-lugsjj and at the otherends pressing upward upon the rack-bar K.

0 0 are screws passingthrough the journallugsjj and engaging with thesprings L L to adjust the pressure of said springs upon the rack-bar K.

M M, Fig. 8, are cams pivoted to the rod J just above the rack-bar K andprovided with arms at m, by means of which arms the cams may be turned.The springs L L press the upper edge of the rack-bar K up against saidcams M.

N is a horizontal rod pivoted to the ends of the arms on m and holdingsaid arms parallel to each other. 1

n. is a lug extending vertically downward from the center of the rod N.

b is a lug extending from the face of the rack-bar K and adapted tolimit the motion of the arms at at, so that they shall not swing to theleft beyond the perpendicular.

P P are metal strips provided with longitudinal slots and screws passingthrough said slots into the top plate of the machine, whereby saidstrips may be adjusted to different positions in the direction of theirlengths. p 1) are lugs formed at the ends of said strips, which aretoward each other. The strips P P are so located upon the top plate ofthe machine that the lugs a shall strike against the lugs P P when thepaper-carriage is near either end of its travel.

Q, Fig. at, is a horizontal slot cut in the rear face of the rod J andextending the entire length of said rod.

(1 is a pin secured rigidly to the top plate of the machine at its lowerend near the back of said top plate and midway between its two sides.The top of the pin qis bent to a horizontal position and extends intothe slot Q, whereby the rod J is held in one horizontal plane.

R is a metal plate.

'1' r are screws passing through holes in the plate R and secured to thetop plate of the machine.

5 s are spiral springs passing around the shanks of the screws 1' r andpressing the plate R against the under surface of the top plate of themachine.

S is a toothed wheel mounted in a hanger T and extending through a slotin the top plate of the machine to engage with the teeth on the loweredge of the rack-bar K.

t is a circular series of teeth formed upon the inner face of the wheelS. The faces of the teeth composing said series, which face in apositive direction, are perpendicular to the plane of the wheel and theother faces are slanting.

U is a lever pivoted at one end to a hanger it upon the plate R.

V is a spiral tension-spring secured at one end to the plateR and at theother end to the free end of the lever U.

A pawl (indicated by dotted lines at Y) is secured to the side of thelever U which is toward the wheel S and is adapted to engage with theteeth 15.

Wis aribbon-spool-aet'uatin g rod supported in the usual manner inhangers o v.

w w are arms. Each of said arms is secured to the rod V by an eyepassing over said rod, so that said arm may turn independent of said rodand so that said rod maybe moved longitudinally in said eye to themotionof the ribbon-spools. The other end of each of the rods 10 w isimmovably secured to the rod X, which rod is held in a horizontalposition by said arms. The arms '20 w are placed a distance apart whichbrings them against the interior faces of the hangers 'v '1'.

Z is a rod connecting the center of the lever U with the rod X.

2 is the usual rod extending transversely under the type-key levers atthe rear of the machine.

3 3 are wires connecting the ends of the rod 2 with the ends of the rodX.

t is an auxiliary key constructed like the type-keys and located at theside of the machine outside of the yoke formed by the rod 2 and wires 33.

5 is alever pivoted to one side of the frame of the machine at the rearand extending horizontally toward the other side of the machine.

(3 is a wire extending perpendicularly from the auxiliary key 4 andconnecting said key with the movable end of 'the lever 5.

7 is a rod connecting the lever 5 with the hanger T.

S is a rack-bar supported by the plate R upon standards 9 9. Saidstandards pass through holes in the top plate of the machine and supportsaid rack above said top plate and in a slot a in the rod J. The teethof the rack-bar 8 have perpendicular faces toward the left-hand side ofthe machine, the other faces of said teeth being slanting.

10, Fig. 5, is a pin adapted to reciprocate in a vertical aperture atthe center of the rod J and engaging at its lower end with the teeth ofthe rack 8 to form a detent, thus preventing any accidental movement ofthe papercarriage toward the right of the machine.

11 is a vertically-extending slot through the face of the rod J into theaperture at the top of the pin 10.

12 is a pin extending from the top of the pin 10 over and resting uponthe upper edge of the rack-bar K.

13 is a spiral spring in the aperture above the pin 10, adapted to pressdownward upon the top of said pin.

1: c is a hanger extending from the plate R and having a slot in it inwhich the lever U plays. The ends of said slot limit the motion of thelever U.

The operation of the abovedescribed device is as follows: lVhen atype-key or the spacing-key is struck, the rod 2 is forced down,carrying with it the rod X by means of the wires 3 3, the arms to toturning about the ribbon-spool-actuating rod \V. The shaft X draws thelever U down by means of the rod Z. The pawl upon the lever U is thuscaused to engage with another of the teeth if.

'When the key isreleased, the spring V draws the rod Uup again, turningthe wheel S onetenth of an inch (the distance between two adjacentletters upon a type-written manuscript.) The wheel S drives the rack-barK to the left a distance equal to its own peripheral movement, thusmoving the paper-carriage of the machine. Then the paper-carriage nearsthe position corresponding to the end of a line of the manuscript, thelug it comes into contact with the lug p at the left of the machine, thearms m m are turned, thereby turning the cams M M, as shown in Fig. 9.The springs LL then raise said rackbar, carrying its teeth out ofengagement with the teeth of the wheel S. The rack-bar K in rising liftsthe pin 12, raising the pin 10 out of engagement with the teeth of therack-bar 8. The paper-carriage, now being free to move toward the rightof the machine, is drawn rapidly to that position by the spring I,acting in a manner entirely analogous to the manner in which it hasheretofore acted to draw the paper-carriage'to the left-hand side of themachine. riage approaches the right-hand side of the machine, the lug nstrikes against the lug p at that side of the machine, the cams M M areturned, thereby forcing the rack-bar K down until its teeth again engagewith the teeth of the wheel S, and the pin 10 is driven down by thespring 13 until the lower end of said pin again engages with the teethof the rack-bar 8. Should it be desirable to return the paper-carriageto the right-hand side of the machine before a line is completed, theoperator presses upon the auxiliary key 4, drawing down upon the lever 5and upon the rod 7, thus drawing the plate R down along the guide-screws0' 1, thus carrying the teeth of the wheel S out of engagement with theteeth of the rack-bar K and the teeth of the rack-bar 8 out ofengagement with the end of the pin 10, afterwhich the paper-carriage isreturned to the right-hand side of the machine, as before described.

The wheel S and lever U may be replaced by various equivalentdevices-as, for instance, that shown in Fig. 10, in which S is a pair oftoggle-levers pivoted at one end of the plate R and at the other end toa block or cross-head 15, sliding in guides ina slot through the plateR. 16 is a pawl upon the block 15, which extends through a slot in thetop plate of the machine and engages with When the papercar-- theratchet-teeth of the rack-bar K. The rod Z is pivotall y secured at thejunction of the toggle-levers S. 17 is a swinging frame depending fromthe plate R. V is a spring acting to press upward on the rod Z, itslower end being supported by the cross-bar of the swinging frame 17.Instead of the swinging frame 17 and spring V, a spring secured at oneend to the plate R and at the other end to the arm to, as shown indotted lines in Fig. 5, may be used.

The mechanism by which the platen is antomatically turned to provide forthe spacing of the lines of the manuscript is described as follows: 1818, Fig. 1, are the sliding pieces which bear the platen when it isshifted to provide for the writing of upper or lower case letters. 19 isa lever pivoted hack of the platen at 20 to that one of the slidingpieces 18 which is toward the right-hand side of the machine and adaptedto be oscillated about said pivot in a vertical plane at right angles tothe line of motion of the paper-carriage. 21 is the usual toothed wheelsecured at one end of and concentric with the platen. 22 is aspring-click the movable end of which engages with the teeth of thewheel21. 23 is a toothed wheel secured to the same axis of the platenand next to the right-hand bearing of said axis. The teeth of the wheel23 are provided with radial and slanting faces, the radial faces beingupward at the portion of said wheel which is toward the rear of themachine. 24 is a pawl adapted to engage with the teeth of the wheel 23and rigidly secured to a shaft bearing in and passing through theforward end of the lever 19. '25 is a thumb-piece secured to the sameshaft as the pawl 24 upon the opposite side of the lever 10 andextending from said shaft toward the front of the machine. 26 is aspring attached at one end of the lever 19 and at the other end pressingupward upon the thumbpiece 25, thus holding the pawl 24 in engagementwith the teeth of the wheel 23. 27 is a lever pivoted at 28 to thesliding piece 18 and provided with a lug 29, adapted to limit the upwardmovement of the forwardly-extending arm of the lever 19. The lever 19 isbent so as to bring its inner end to and parallel to the top plate ofthe machine. 30 is the sliding piece adapted to limit the motion of thepapercarriage to provide for the desired width of the margin of themanuscript. 31 is a metal plate secured to the sliding piece 30 inavertical plane parallel to the line of travel of the paper-carriage andhaving its upper edge in an inclined plane, as shown in Figs. 3 and 4.

The operation of the above-described device for automatically turningthe platen is as follows: When the paper-carriage is drawn back, asabove described, the end of the lever 19, which is toward the rear ofthe machine, strikes against and rides upon the inclined edge of theplate 31, forcing down the forward end of said lever and turning thewheel 23, and therefore the platen, by means of the IIO pawl 24. Theposition of the lever 27 determines whether the lines of the manuscriptshall be near together or wide apart by lin1iting the upward movement ofthe forward arm of the lever 19 in the usual manner. A lug 32 maybeformed upon the lever 27, adapted to engage with notches 33 to hold saidlever in different positions. The rearwardlyextending arm of lever 19should be slightly bent to the left, as shown in Fig. 1, so that itshall not pass entirely over the plate 31. By pressing upon thethumb-piece 25 the pawl 2* may be disengaged from the teeth of the wheel23, leaving the platen free to turn.
